Description
TECHNICAL FIELD
[0001] The present invention belongs to the technical field of
electronic cigarettes, and particularly relates to an ultrasonic
electronic cigarette atomizer.
BACKGROUND ART
[0002] The existing ultrasonic electronic cigarette atomizer
comprises an atomizer shell, a suction nozzle connected with the
top end of the side wall of the atomizer shell, and an atomization
piece, a liquid guide structure and a tobacco tar storage cavity in
the atomizer shell, the liquid guide structure communicates with
the tobacco tar storage cavity, and the liquid guide structure is
in contact with one side surface of the atomization piece and is
used for guiding tobacco tar to the surface of the atomization
piece for atomization.
[0003] The existing ultrasonic electronic cigarette atomizer has
the following disadvantages:
[0004] Firstly, it takes some time for the atomization piece to
rise from the normal temperature to the working temperature, namely
the atomization piece cannot immediately atomize the tobacco tar to
produce smoke after being electrified, therefore the smoke of an
electronic cigarette is insufficient at the beginning of use, a
smoker cannot inhale the smoke or can only inhale a small amount of
smoke for the previous puffs, and thus the user experience is
poor.
[0005] Secondly, the structural design is unreasonable, the number
of hollow cavities in the atomizer shell is small, and the volume
of the hollow cavity is small, therefore the high temperature
produced by the atomization piece at work is transferred to the
atomizer shell easily, such that the surface of the atomizer shell
becomes burning hot, resulting in discomfort of the user during
hand holding.
Contents of Invention
[0006] The existing electronic cigarette atomizer lacks smoke at
the beginning of use, and meanwhile an atomizer shell is liable to
become burning hot, therefore the user experience is poor. The
objective of the present invention is to provide an improved
ultrasonic electronic cigarette atomizer in view of the above
shortcomings of the prior art, in which the atomization speed is
high, a larger amount of smoke can be obtained at the beginning of
inhalation, the temperature of the atomizer shell is low, and
user's comfort when inhaling is high.
[0007] In order to solve the above-mentioned technical problems,
the technical solution adopted by the present invention is as
follows:
[0008] An ultrasonic electronic cigarette atomizer comprises an
atomizer shell, and an atomization piece and a liquid guide
structure are arranged in the atomizer shell; the liquid guide
structure communicates with a liquid storage cavity in the atomizer
shell; the ultrasonic electronic cigarette atomizer is structurally
characterized in that a heating body is further arranged in the
atomizer shell, both of the atomization piece and the heating body
are in contact with the liquid guide structure, and both of the
heating body and an atomization surface of the atomization piece
communicate with an airflow passage, and a positive electrode and a
negative electrode of the heating body are respectively connected
with one end and the other end of a power supply.
[0009] By means of the above structure, the heating body serves as
an auxiliary heating structure and can perform auxiliary heating on
tobacco tar on atomization cotton or heat the atomization piece,
thereby increasing the temperature rise speed of the tobacco tar or
the working temperature rise speed of the atomization piece,
accordingly the electronic cigarette can atomize the tobacco tar at
the beginning of work so as to produce smoke, the problem in the
prior art that the smoke cannot be produced when the atomization
piece is started up is solved, and the user experience is good.
Meanwhile, the heating body can also directly heat the tobacco tar
until the smoke is produced, thereby increasing the amount of
smoke. Moreover, as the temperature of the tobacco tar on the
atomization cotton is relatively high, the flow speed of the
tobacco tar is relatively high, therefore sufficient supply of the
tobacco tar during atomization can be guaranteed, and the dry
burning problem caused by insufficient supply of the tobacco tar is
avoided.
[0010] As a preferred mode, the liquid guide structure comprises
atomization cotton in contact with one side surface of the
atomization piece, both of the atomization piece and the
atomization cotton are fixed on an atomization core bracket, and
the atomization cotton is clamped between the heating body and the
atomization piece.
[0011] Further, one end of the side wall of the atomizer shell is
connected with a suction nozzle, a washer and a pressing ring,
which are detachably connected with each other, are arranged in the
atomization core bracket, the atomization cotton is of a flaky
structure, and the atomization piece is arranged to be parallel to
the length direction of an electronic cigarette; the atomization
piece is fixed in the washer, one end of the atomization cotton is
arranged between the washer and the pressing ring, and the other
end of the atomization cotton extends into a tobacco tar bottle; a
projection which abuts against the heating body is arranged on the
pressing ring; a first hollow cavity which communicates with the
suction nozzle is formed between the pressing ring and the
atomization cotton; an air pass groove which communicates with the
outside and is parallel to the length direction of the electronic
cigarette is formed in the side wall, away from the atomization
piece, of the pressing ring, an air pass hole is formed in a
position in a position in the pressing ring, the position in the
pressing ring corresponds to one end, away from the suction nozzle,
of the atomization piece, and the air pass hole communicates the
air pass groove and the first hollow cavity.
[0012] As the air pass groove is formed, when an atomization core
is placed in the atomizer shell for use, a third hollow cavity for
heat insulation is formed between the pressing ring and the side
wall of the atomizer shell, therefore the temperature produced by
the atomization piece at work is unlikely to be transferred to the
atomizer shell through the pressing ring, thereby reducing the
working temperature on the surface of the atomizer shell. As the
air pass groove communicates with the suction nozzle, the internal
heat can be taken out by the airflow in time, thereby further
reducing the working temperature on the surface of the atomizer
shell.
[0013] A depressed region is formed in the outer side wall of the
atomization core bracket.
[0014] By means of the above structure, when the atomization core
is placed in the atomizer shell for use, a fourth hollow cavity for
heat insulation is formed between the atomization core bracket and
the side wall of the atomizer shell, therefore the temperature
produced by the atomization piece at work is unlikely to be
transferred to the atomizer shell through the atomization core
bracket, thereby reducing the working temperature on the surface of
the atomizer shell.
[0015] Further, a second hollow cavity is formed between the
atomization piece and the washer.
[0016] Due to the arrangement of the second hollow cavity, the
temperature produced by the atomization piece at work is unlikely
to be transferred to the atomizer shell through the washer and the
atomization core bracket, thereby reducing the working temperature
on the surface of the atomizer shell.
[0017] Further, a tobacco tar bottle placing cavity which places
the tobacco tar bottle is formed in one end, away from the suction
nozzle, of the atomization core bracket.
[0018] By means of the above structure, the tobacco tar bottle is
embedded in the atomization core bracket to form an integrated
structure so as to facilitate the production and assembly.
[0019] As a preferred mode, the heating body is in contact with a
position, aligned to the central area of the atomization piece, of
the atomization cotton, or the heating body is in contact with a
position, close to a tobacco tar cup, of the atomization
cotton.
[0020] If the heating body is in contact with the position, close
to the tobacco tar cup, of the atomization cotton, namely the
heating body is in contact with the position where the atomization
cotton just comes out from the tobacco tar bottle, more tobacco tar
can flow more quickly.
[0021] As a preferred mode, the heating body is an electric heating
piece or a disc-shaped electric heating wire.
[0022] Further, a wiring groove is formed in the atomization core
bracket.
[0023] During production, electronic wires run through wiring
grooves so as to guarantee that the electronic wires will not be
broken during the production to cause a short circuit phenomenon.
Meanwhile, as the wiring grooves are embedded in the atomization
core bracket, an integrated structure is formed to facilitate the
production and assembly.
[0024] Further, a sealing pad is arranged in the suction
nozzle.
[0025] The sealing pad is embedded in the suction nozzle so as to
guarantee that an air inlet passage and an air outlet passage will
produce no gas leakage phenomenon at work.
[0026] As another preferred mode, the heating body is arranged on
the surface of the atomization piece and is in contact with the
atomization piece.
[0027] As a preferred mode, the atomization piece, the heating body
and the liquid storage cavity are sequentially arranged along
outflow direction of the atomized gas.
[0028] The liquid storage cavity is formed above the atomization
piece, therefore it is more convenient to enable the tobacco tar in
the liquid storage cavity to flow onto the liquid guide
structure.
[0029] As a preferred mode, the airflow passage comprises an air
inlet pipe arranged in the liquid storage cavity and an air outlet
pipe arranged in the air inlet pipe, the air inlet passage is
arranged between the inner wall of the air inlet pipe and the outer
wall of the air outlet pipe; the bottom end of the air outlet pipe
communicates with upper surface of the heating body; the top end of
the air outlet pipe is fixedly connected with a suction nozzle
seat, and the air outlet pipe communicates with the suction nozzle
on the suction nozzle seat; an air inlet hole is formed in the
suction nozzle seat; and the air inlet passage communicates with
the air inlet hole.
[0030] The airflow passage can guarantee that the external air
enters the air inlet passage from an air inlet, and then mixed with
the smoke atomized by the atomization piece at the bottom end of
the air inlet passage, and then conveyed into the oral cavity of
the user through the air outlet pipe and the suction nozzle,
thereby being simple in structure and convenient to
manufacture.
[0031] Further, the liquid guide structure is in contact with the
upper surface of the heating body; the bottom end of the air inlet
pipe abuts against (i.e., contact in a pressure state) the upper
surface of the liquid guide structure through an adjusting
mechanism which controls the throughput of the tobacco tar, and an
air inlet notch is formed in the bottom end of the air outlet pipe;
the air outlet passage is arranged in the air outlet pipe; and the
air inlet passage communicates with the air outlet passage through
the air inlet notch.
[0032] By means of the above structure, it can be guaranteed that
the external air enters the air outlet pipe to take away the smoke
in time so as to prevent the smoke from entering the air inlet
passage to affect the taste of the smoke or cause a condensed
tobacco tar accumulation phenomenon.
[0033] As a preferred mode, the adjusting mechanism comprises an
elastic adjusting sleeve and a top seat; the upper end of the
elastic adjusting sleeve is arranged between the air inlet pipe and
the liquid storage cavity, and the bottom end of the air inlet pipe
is in contact with the elastic adjusting sleeve; at least one
liquid supply hole which communicates with the liquid guide
structure is formed in the upper end of the elastic adjusting
sleeve; the atomization piece, the heating body and the liquid
guide structure are all provided in the inside of the lower end of
the elastic adjusting sleeve; and the inner wall of the top seat is
in threaded connection with the air inlet pipe.
[0034] The air inlet pipe can be rotated by the top seat, so the
air inlet pipe produces an axial displacement to compress the
elastic adjusting sleeve so as to control the pressing force
applied to the liquid guide structure by the bottom of the air
inlet pipe, thus the throughput of the tobacco tar can be
controlled to prevent excessive tobacco tar from being soaked on
the surface of the atomization piece to affect the atomization
effect. Meanwhile, the elastic adjusting sleeve can relieve or
isolate the high temperature produced in an atomization process
from being transferred to the air inlet pipe so as to prevent the
air inlet pipe from transferring the heat to the atomizer shell to
avoid the phenomenon that the atomizer becomes burning hot.
[0035] As a preferred mode, the liquid guide structure comprises
porous material; the liquid supply hole is covered by or filled
with the upper surface of the porous material; and both of the
liquid storage cavity and the elastic adjusting sleeve are arranged
in the atomizer shell.
[0036] The elastic adjusting sleeve can seal and fix the
atomization piece to prevent the leakage of the tobacco tar, and
meanwhile the phenomenon that the atomization piece is stuck and
cannot vibrate can be prevented.
[0037] As a preferred mode, the heating body is a heating wire or
heating piece, the heating wire or the heating piece is embedded on
the upper surface of the atomization piece; or the heating body is
a netlike heating wire, and the netlike heating wire is superposed
on the upper surface of the atomization piece.
[0038] The heating body and the atomization piece can be an
integrated structure and can also be a superposed structure,
thereby being simple to manufacture.
[0039] Further, the lower surface of the atomization piece is in
contact with a plurality of elastic ejector pins; the elastic
ejector pins are fixedly connected with an atomization bottom seat;
and the lower end of the elastic adjusting sleeve is arranged in
the atomization bottom seat.
[0040] The elastic ejector pins can ensure more stable and reliable
internal electrical connection of the atomizer, compared with the
electric conduction mode of electronic wires, the elastic ejector
pins can prevent the high temperature produced by the atomization
piece at work from melting a bonding pad to cause drop of the
electronic wires and produce an open circuit phenomenon.
[0041] Further, an adjusting device which adjusts the airflow
volumes of the air inlet hole is arranged on the suction nozzle
seat.
[0042] The air inlet volume of the air inlet can be adjusted by the
adjusting device, therefore the taste of the atomized gas can be
improved.
[0043] Further, a tobacco tar injection opening is formed in the
liquid storage cavity.
[0044] When there is no tobacco tar in the liquid storage cavity,
the tobacco tar can be conveniently supplemented through the
tobacco tar injection opening.
[0045] Compared with the prior art, the heating body of the present
invention can not only quickly heat the tobacco tar to approach to
its atomization temperature, but also can transfer a part of heat
to the atomization piece, so that the atomization piece quickly
starts to atomize the tobacco tar, therefore the atomization
starting time is shortened, the atomization efficiency is high, the
amount of smoke is large, the atomizer will not become burning hot,
energy is saved, the user can obtain a larger amount of smoke at
the beginning of smoking, the temperature of the atomizer shell is
low, the atomization taste is purer, no burnt flavor is produced,
and no hazardous substance will be produced by heating tobacco tar
guide cotton, fibers or other tobacco tar guide materials; the
structure is simple and ingenious, and the manufacture and use are
convenient; and no pinhole needs to be provided in the atomization
piece of the present invention to eject the atomized smoke,
therefore the situation that the atomized smoke cannot be ejected
when the gas is atomized because larger liquid molecules block the
pinhole will not occur, and meanwhile the tobacco tar leakage of
the atomizer can be better prevented.
